The Paleontological Museum of Montevarchi is a paleontological museum located in Montevarchi, belonging to the Accademia Valdarnese del Poggio and founded in 1819.
In the museum are collected about 3000 artifacts, coming almost exclusively from the Upper Valdarno and aged between the Upper Pliocene and Lower Pleistocene.
The collection includes vegetable fossils, such as the nuts of Junglans tephrodes and the leaves of Platanus aceroides, and a rich collection of animal fossils. Among these are the Elephas meridionalis, an imposing proboscidean that could exceed 4 metres at the withers and weigh up to 200 quintals, and the skull of Machairodus meganteron, the so-called "sabre-toothed tiger", so called because of the size of its upper canines.
